Definitions
- the present invention relates to a method and an arrangement for the removing of goods from a package in accordance with the preamble of the independent claims.
- US-A-3 260 404 Previously known technology which can be used to remove material from a package is shown in US-A-3 260 404.
- the patent shows an apparatus in which material is removed from the successive pockets by means of jets of air from conduits (33, 34 and 35). This does not correspond with the invention which calls for moving a discharge device at the discharge station transversely of the package band in a particular way in order to discharge the articles from the pockets.
- the technology disclosed in US-A-3 260 404 does not fulfil the requirement of removing the goods by mechanical means, a requirement made in order to obtain reliable function especially when removing heavy articles.
- FR-A-2 124 201 shows an arrangement for expelling liquids or powder from a pocket in which a rotatable roller which is fixed in position acts on diagonal pockets 2 to expel the liquid or the powder from the pockets as shown in Fig. 1.
- Fig. 3 shows a roller which acts on a single pocket to remove the content therefrom by means of a hand-operated crank mechanism which displaces roller 28 lengthwise of the pockets.
- the embodiment shown in Fig. 3 is inapplicable to the invention which operates on successive pockets and relies upon displacement of a discharge means along the pockets to remove the articles, the operation being carried out on successive pockets.
- the reference does not disclose any correspondence to the cutting means 67 which is cutting the package band 24 to form the emptying openings 25 of the pockets 16.
- the present invention indicates a method and an arrangement which fulfil the needs and demands put forward. It is a particularly valuable feature of the present invention that it makes possible a simple, reliable and rational discharging of components and/or parts from packages and in addition to this a simple adapting of the discharge of the components or parts in accordance with the working phase occurring at the particular assembling station.
- Fig. 1-3 is represented an embodiment of a package band 10 formed of a band of flexible material, generally plastic material.
- the band of flexible material has been folded over so that two walls 11a, 11b placed substantially adjoining one another are formed, referred to hereinafter generally as first wall 11a and second wall 11b respectively.
- Each one of the walls has a first edge area 12a and 12b respectively. These two edge areas together form the first edge area 12 of the package band.
- Each one of the first edge areas 12a and 12b of the walls is provided with a connecting means 17a, 17b which in the figures is in the form of a tunnel 17a, 17b. Following the second edge area 14 of the package band the two walls blend into one another in a transition 23.
- a joint 13 provided in longitudinal direction of the band fixes the walls to one another in an area inside of, and parallel to, the transition 23 of the band.
- a tunnel 18 is formed between the joint 13 and the transition just mentioned, which constitutes a second connecting element 18 on the package band.
- Substantially transversely to the longitudinal direction of the band joints 15 are provided parallel with one another, which fix the two walls 11a, 11b to one another and are jointed to, or substantially reach as far as, the joint 13 arranged in longitudinal direction of the band.
- the said joints 13 and 15 thus delimit a number of pockets 16 arranged following one another in longitudinal direction of the band which are oriented transversely to the longitudinal direction of the band.
- the joints referred to above are realized e.g. as welded or bonded joints.
- the joints 15 situated transversely to the band terminate before they attain the connecting means 17a, 17b of the respective wall 11a, 11b.
- a striplike area 19a, 19b is formed in longitudinal direction of the band on each of the walls where these are not fixed to one another. This means that in an area comprising the striplike area just mentioned and the connecting elements 17a, 17b in the first edge area 12 of the package band, the walls can be moved from one another so as to facilitate access to the pockets 16.
- the distance between the longitudinal joint 13 provided in the second edge area 14 and the end of the transverse joints 15 closest to the joint is chosen so that between the joints 15 and the joint 13 openings 22 are formed of a size adapted to the dimensions of a mechanical means e.g. an arm or a finger, this means forming part of an emptying equipment for the discharge of goods stored in the pockets 16.
- the joint 13 consequently represents an alternative embodiment of the second connecting means 18.
- Fig. 4a-f and in Fig. 5 is shown an example of a technique for the feeding of goods into the pockets 16 of the package band.
- Fig. 4a-f are shown sectional views of the package band corresponding to the section III-III in Fig. 2 during different stages of the feeding of goods into one of the pockets 16a.
- the goods are represented in this instance by the items 50a-50e.
- a feeding board 30 is provided in a preferred application which e.g. may be in the form of a belt conveyor with a direction of movement transversely to the plane of projection.
- Fig. 4a-e correspond to the position of the package band as shown in Fig.
- Fig. 4f corresponds to the position the package band occupies when it has moved one or more steps to the left of that shown in Fig. 5 so as to make possible the closure of the pocket 16a filled with goods and the feeding of goods into a subsequent pocket.
- Fig. 4f also shows how in certain applications the transport band of the belt conveyor in this area and/or the board has a bent-off part 31 so as to make room for e.g. welding dies 33, 34 by means of which the two walls of the package band are fused together and are fastened so as to provide a closure of the pocket filled with goods.
- the welding dies are designed so as to sever at the same time the connecting means 17a, 17b alongside with, as a rule, adjoining parts of the striplike area 19a, 19b from the closed band.
- Fig. 4-5 are shown forkshaped format arms 40a, 40b which are located in the connecting means 17a, 17b designed as tunnels of the walls 11a, 11b in the first edge area 12.
- Each one of the format arms comprises a first portion 41, 41b which via a transition portion 42a, 42b passes over into a second portion 43a, 43b.
- the format arms in their first portions are located at a distance from one another whilst in their second portions they are located adjacent to one another.
- the package band is moved in the direction of the arrow A ( Figure 5) which is done by means not shown in the Figure.
- the first portions of the format arms keep the connecting means 17a, 17b of the walls 11a, 11b away from one another as a result of which the pocket or pockets 16 which are in the corresponding part of the package band become accessible to allow feeding in of goods.
- the Figures 4a-f show schematically how in this position items 50a-50e are successively moved into the pocket 16a.
- the feeding takes place either purely manually or with the help of a device not shown in the Figures which preferably pushes the items in piece by piece. A succeeding item then pushes an item already there towards the bottom of the pocket so that when all items have been delivered they occupy a position corresponding to that which is shown in Fig. 4e.
- the package band may have a vertical orientation, with the items dropping down into the pocket.
- the package band is moved one or more steps towards the left in Fig. 5 and the pocket 16a provided with goods is closed by e.g. welding means 33, 34 so that a joint 21 is formed between the walls, and at the same time the connecting means 17a, 17b in the first edge area of the respective walls, and in certain applications also adjoining parts of the striplike area 19a, 19b, are severed from the package band whilst a succeeding pocket 16 in the band occupies the position where goods are supplied to it.
- the reference designation 24 will be used for a package band filled with goods (see Fig. 6).
- Fig. 6-9 is shown an embodiment of an arrangement for the discharge of goods present in pockets 16 of the package band 24.
- the discharge arrangement comprises a stand 70 which supports a base 60, hereinafter referred to as discharge base 60.
- This as a rule is constituted of a rectangular board or of a conveyor belt.

- the package band is moved from the first end area of the discharge base to its second end area in order to allow a discharging device 71 in an area in between to remove goods 50 from pockets 16 of the package band.
- the arrangement includes a retaining means 64 which in the embodiments illustrated in the Figures is in the form of an arm located at a small distance from the boundary surface 79 of the discharge base 60 and adjoining a first edge area 77 of the discharge base.
- a first cutting means 65 is provided following the retaining means 64 and located in an area substantially between the discharging device 71 and the second end area 76 of the discharge base or located in this end area.
- a front retaining and control means 66 herein - after called control means.
- a receiving means 82 for goods discharged from the package band is provided following the second edge area 78 of the discharge base or is formed by a part of the latter.
- the receiving means is located in the area of the discharging device 71 so as to co-operate with the discharging device during the discharge of goods from the package band.
- the receiving means is designed as a receiving board 62 or a receiving track 62 according to the embodiments illustrated in the Figures.
- the receiving track is oriented substantially at right angles to the direction of movement of the package band and connects to the second edge area 78 of the discharge base 60.
- the discharge table is delimited by a chute wall 63a, 63b.
- a second cutting means 67 is provided in connection with the front control means 66 and is located in an area which precedes the area for the receiving board 62 when the package band travels from the first end area 75 of the discharge base to the second end area 76 of the discharge base.
- the front control means 66 too is located in an area which precedes the area of the receiving means 82.
- the Figures illustrate the manner in which the discharging device 71 is arranged so that it can move substantially transversely to the direction of travel of the packing belt and in a direction towards and away from the receiving board 62.
- the discharging device according to the embodiment shown includes an arm 72 connected with a fork 73 wherein is supported a contact means 74 which in the Figures is shown in an embodiment where it is constituted of a pusher roll 74.
- the pusher roll On displacement of the discharging device in the direction towards the receiving board the pusher roll describes a track along the discharge base 60.
- the discharging device as a rule comprises e.g. a spring which maintains the pusher roll pressed against the base which during the discharge of the goods is constituted of the second wall 11b of the package band.
- FIG. 1 An embodiment of the arrangement where a transporting means 68a, 68b for the movement of the package band is arranged following the second end area 76 of the discharge base.

- the rolls are supported in one or several motor and bearing housings 69.
- the goods are inserted into pockets 16 of the band in that the format arms 40a, 40b (see Fig. 5) are introduced into the connecting means 17a, 17b, separate for the respective walls 11a, 11b, whereupon the belt is moved by transporting means (not shown in the figures) along the format arms in the direction of the arrow A in Fig. 5. Since the format arms in the first portion 41a, 41b are situated at a distance from one another, the connecting means occupy a position at a distance from one another, which implies that the packing pocket or pockets 16 which are in a position corresponding to the position of the first portion 41a, 41b of the format arms will be accessible for the feeding in of goods.
- the joint 21 between the two walls is formed in the striplike area 19a, 19b, the joint being placed so that the distance to the nearest joint 15 arranged transversely to the longitudinal direction of the web is less than the smallest dimension of the items. In this manner any movement of items out of the pocket into which they have been introduced, after closure of the pockets, is prevented.

- the retaining means 64 and the front control means 66 ensure that the package band is extended transversely to the longitudinal direction of the track.
- the second cutting device 76 opens the package band adjoining the joint 21 which was formed while closing the package band. As a result an opening 25 is formed for each of the pockets 16 to allow goods which are stored in them to leave the pockets.
- the first edge area 12 of the closed package band 24 is provided with a connecting means e.g. a tunnel or material thickenings which interacts with the control means.
- a connecting means e.g. a tunnel or material thickenings which interacts with the control means.

- the contact means 74 of the discharging device When the first pocket 16 with components reaches the position straight before the receiving means 82 (receiving board or receiving track 62) the contact means 74 of the discharging device is moved transversely to the longitudinal direction of the package band whilst resting against the second wall 11b of the package band which in turn is pressed by the contact means against an edge or wall of the component stored in the pocket farthest from the opening of the pocket, the edge or wall facing towards the contact means. As a result the components are pushed out of the pocket by the contact means and are placed e.g. on the receiving board 62. When the package band has been advanced one position, the next pocket is emptied of its contents. In certain applications the discharge of components is controlled with a view to the presence, or the number, of components on the receiving board.

Description
- The present invention relates to a method and an arrangement for the removing of goods from a package in accordance with the preamble of the independent claims.
- There is a need in industrial context for making it possible in manufacturing processes to move components and/or parts to a certain position from which they can be picked up in each individual phase of assembly in order to be fitted to the equipment in course of manufacture. It is necessary in certain applications for the components or parts prior to assembly to be protected from contaminations and pollution as long as possible. It is also desirable for the parts which are to be assembled to be removed from the packages by mechanical means and to be made accessible in batches, the number of parts included in each batch having to correspond to the number which is to be assembled in each individual phase of assembly. It is desirable, moreover, in certain assembly operations for the components or parts, after they have been removed from the packages, to be mutually in order and position so that e.g. a robot can be adjusted in order to pick up the parts and assemble them.
- Previously known technology which can be used to remove material from a package is shown in US-A-3 260 404. The patent shows an apparatus in which material is removed from the successive pockets by means of jets of air from conduits (33, 34 and 35). This does not correspond with the invention which calls for moving a discharge device at the discharge station transversely of the package band in a particular way in order to discharge the articles from the pockets. The technology disclosed in US-A-3 260 404 does not fulfil the requirement of removing the goods by mechanical means, a requirement made in order to obtain reliable function especially when removing heavy articles.
- FR-A-2 124 201 shows an arrangement for expelling liquids or powder from a pocket in which a rotatable roller which is fixed in position acts on diagonal pockets 2 to expel the liquid or the powder from the pockets as shown in Fig. 1. Fig. 3 shows a roller which acts on a single pocket to remove the content therefrom by means of a hand-operated crank mechanism which displaces roller 28 lengthwise of the pockets. The embodiment shown in Fig. 3 is inapplicable to the invention which operates on successive pockets and relies upon displacement of a discharge means along the pockets to remove the articles, the operation being carried out on successive pockets. The reference does not disclose any correspondence to the cutting means 67 which is cutting the
package band 24 to form theemptying openings 25 of thepockets 16. - The present invention indicates a method and an arrangement which fulfil the needs and demands put forward. It is a particularly valuable feature of the present invention that it makes possible a simple, reliable and rational discharging of components and/or parts from packages and in addition to this a simple adapting of the discharge of the components or parts in accordance with the working phase occurring at the particular assembling station.

- In Fig. 1-3 is represented an embodiment of a
package band 10 formed of a band of flexible material, generally plastic material. The band of flexible material has been folded over so that twowalls first wall 11a andsecond wall 11b respectively. Each one of the walls has afirst edge area first edge area 12 of the package band. Each one of thefirst edge areas connecting means tunnel second edge area 14 of the package band the two walls blend into one another in atransition 23. - A
joint 13 provided in longitudinal direction of the band fixes the walls to one another in an area inside of, and parallel to, thetransition 23 of the band. As a result atunnel 18 is formed between thejoint 13 and the transition just mentioned, which constitutes a second connectingelement 18 on the package band. Substantially transversely to the longitudinal direction of theband joints 15 are provided parallel with one another, which fix the twowalls joint 13 arranged in longitudinal direction of the band. The saidjoints pockets 16 arranged following one another in longitudinal direction of the band which are oriented transversely to the longitudinal direction of the band. The joints referred to above are realized e.g. as welded or bonded joints. - The
joints 15 situated transversely to the band terminate before they attain theconnecting means respective wall striplike area elements first edge area 12 of the package band, the walls can be moved from one another so as to facilitate access to thepockets 16. - In certain embodiments the distance between the
longitudinal joint 13 provided in thesecond edge area 14 and the end of thetransverse joints 15 closest to the joint is chosen so that between thejoints 15 and the joint 13openings 22 are formed of a size adapted to the dimensions of a mechanical means e.g. an arm or a finger, this means forming part of an emptying equipment for the discharge of goods stored in thepockets 16. Thejoint 13 consequently represents an alternative embodiment of the second connecting means 18. - In Fig. 4a-f and in Fig. 5 is shown an example of a technique for the feeding of goods into the
pockets 16 of the package band. In Fig. 4a-f are shown sectional views of the package band corresponding to the section III-III in Fig. 2 during different stages of the feeding of goods into one of thepockets 16a. The goods are represented in this instance by theitems 50a-50e. For the feeding in of the goods afeeding board 30 is provided in a preferred application which e.g. may be in the form of a belt conveyor with a direction of movement transversely to the plane of projection. Fig. 4a-e correspond to the position of the package band as shown in Fig. 5 whilst Fig 4f corresponds to the position the package band occupies when it has moved one or more steps to the left of that shown in Fig. 5 so as to make possible the closure of thepocket 16a filled with goods and the feeding of goods into a subsequent pocket. Fig. 4f also shows how in certain applications the transport band of the belt conveyor in this area and/or the board has a bent-offpart 31 so as to make room for e.g. welding dies 33, 34 by means of which the two walls of the package band are fused together and are fastened so as to provide a closure of the pocket filled with goods. In a preferred embodiment the welding dies are designed so as to sever at the same time the connectingmeans striplike area - In Fig. 4-5 are shown
forkshaped format arms means walls first edge area 12. Each one of the format arms comprises a first portion 41, 41b which via atransition portion 42a, 42b passes over into asecond portion 43a, 43b. The format arms in their first portions are located at a distance from one another whilst in their second portions they are located adjacent to one another. The package band is moved in the direction of the arrow A (Figure 5) which is done by means not shown in the Figure. The first portions of the format arms keep the connectingmeans walls position items 50a-50e are successively moved into thepocket 16a. - The feeding in takes place either purely manually or with the help of a device not shown in the Figures which preferably pushes the items in piece by piece. A succeeding item then pushes an item already there towards the bottom of the pocket so that when all items have been delivered they occupy a position corresponding to that which is shown in Fig. 4e. Naturally the package band may have a vertical orientation, with the items dropping down into the pocket.
- Subsequently the package band is moved one or more steps towards the left in Fig. 5 and the
pocket 16a provided with goods is closed by e.g. welding means 33, 34 so that a joint 21 is formed between the walls, and at the same time the connectingmeans striplike area pocket 16 in the band occupies the position where goods are supplied to it. In the description which follows thereference designation 24 will be used for a package band filled with goods (see Fig. 6). - In Fig. 6-9 is shown an embodiment of an arrangement for the discharge of goods present in
pockets 16 of thepackage band 24. The discharge arrangement comprises astand 70 which supports abase 60, hereinafter referred to asdischarge base 60. This as a rule is constituted of a rectangular board or of a conveyor belt. Especially in applications where the arrangement is intended to handle package bands containing heavy goods the use of a conveying belt as a discharge base is preferred. The discharge base on the one hand has afirst end area 75, situated in the feeding-inpart 80 of the arrangement, for the package band filled with goods, and on the other hand it has asecond end area 76 which is situated in thedischarge part 81 of the arrangement. The package band is moved from the first end area of the discharge base to its second end area in order to allow a dischargingdevice 71 in an area in between to removegoods 50 frompockets 16 of the package band. - The arrangement includes a retaining means 64 which in the embodiments illustrated in the Figures is in the form of an arm located at a small distance from the
boundary surface 79 of thedischarge base 60 and adjoining afirst edge area 77 of the discharge base. A first cutting means 65 is provided following the retaining means 64 and located in an area substantially between the dischargingdevice 71 and thesecond end area 76 of the discharge base or located in this end area. In an area close to, and as a rule following, asecond edge area 78 of the discharge base and at a small distance from itsboundary surface 79 is provided a front retaining and control means 66, herein - after called control means. A receiving means 82 for goods discharged from the package band is provided following thesecond edge area 78 of the discharge base or is formed by a part of the latter. The receiving means is located in the area of the dischargingdevice 71 so as to co-operate with the discharging device during the discharge of goods from the package band. - In a preferred embodiment the receiving means is designed as a receiving
board 62 or a receivingtrack 62 according to the embodiments illustrated in the Figures. The receiving track is oriented substantially at right angles to the direction of movement of the package band and connects to thesecond edge area 78 of thedischarge base 60. Along at least one of its lateral edges the discharge table is delimited by achute wall board 62 when the package band travels from thefirst end area 75 of the discharge base to thesecond end area 76 of the discharge base. The front control means 66 too is located in an area which precedes the area of the receiving means 82. - The Figures illustrate the manner in which the discharging
device 71 is arranged so that it can move substantially transversely to the direction of travel of the packing belt and in a direction towards and away from the receivingboard 62. The discharging device according to the embodiment shown includes anarm 72 connected with afork 73 wherein is supported a contact means 74 which in the Figures is shown in an embodiment where it is constituted of apusher roll 74. On displacement of the discharging device in the direction towards the receiving board the pusher roll describes a track along thedischarge base 60. In accordance with the invention the discharging device as a rule comprises e.g. a spring which maintains the pusher roll pressed against the base which during the discharge of the goods is constituted of thesecond wall 11b of the package band. - In the Figures is shown an embodiment of the arrangement where a transporting
means second end area 76 of the discharge base. The transporting means in the embodiment shown is constituted of two rotating rolls placed substantially on top of one another with matching direction of rotation in the area where the circumferential surfaces of the rolls are located closest to one another. The rolls are supported in one or several motor and bearinghousings 69. - When using the band in accordance with the invention the goods are inserted into
pockets 16 of the band in that theformat arms means respective walls items 50a-50e, are inserted successively into the pockets, each succeeding item pressing the foregoing item in the the direction towards the bottom of the pocket. In each application the dimensions of thepocket 16 are chosen so that the inner cross-section of the pocket in expanded state does not permit two items to be wholly or partly on top of one another. Similarly the length of the pocket is adapted to the combined length of the items intended for a pocket in such a manner that the combined length of the items is only insignificantly less than the length of the pocket. Subsequently the joint 21 between the two walls is formed in thestriplike area striplike areas package band 24 filled with goods has been formed. - When the
package band 24 is to be emptied it is passed to the arrangement according to Fig. 6-9 . As a rule the package band is drawn by the transportingmeans part 80 of the arrangement to thedischarge part 81 of the arrangement. At the start of the feeding in of the package band the second connectingmeans 18 are guided in position so as to cooperate with the retaining means 64. At the same time the front control means 66 is introduced into the closed package band up to theclosure 21 and occupies there a position alongside the package band between the twowalls striplike area second end area 76 of the discharge base, thesecond cutting device 76 opens the package band adjoining the joint 21 which was formed while closing the package band. As a result anopening 25 is formed for each of thepockets 16 to allow goods which are stored in them to leave the pockets. - In applications where the goods stored in the pockets have a shape which could cause the control means 66 to stick to the goods, as a rule the
first edge area 12 of theclosed package band 24 is provided with a connecting means e.g. a tunnel or material thickenings which interacts with the control means. Preferably the connecting means is made in connection with the closing of the filled package band, e.g. by means of the welding dies 33, 34. - When the
first pocket 16 with components reaches the position straight before the receiving means 82 (receiving board or receiving track 62) the contact means 74 of the discharging device is moved transversely to the longitudinal direction of the package band whilst resting against thesecond wall 11b of the package band which in turn is pressed by the contact means against an edge or wall of the component stored in the pocket farthest from the opening of the pocket, the edge or wall facing towards the contact means. As a result the components are pushed out of the pocket by the contact means and are placed e.g. on the receivingboard 62. When the package band has been advanced one position, the next pocket is emptied of its contents. In certain applications the discharge of components is controlled with a view to the presence, or the number, of components on the receiving board. In certain applications the presence of components on the receiving board or its equivalent is monitored by means of a detector arrangement, the discharge from a pocket taking place only when no components are present on the receiving board or when a number of components specified in advance has been recorded on the receiving board. - During the movement towards the discharge end of the arrangement the connecting means 18 located in the
second edge area 14 of the package band passes the first cutting means 65 which opens the connectingmeans 18. This makes it possible for the band to leave the retaining means 64. The band, thereafter, continues between the two displacement means 68a, 68b and the used band is stored e.g. in acontainer 61. - In some embodiments of the package band one or more of the connecting
means pockets 16 the walls of the package band in such cases pass through slits e.g. in the walls of pipes. The width of the slits in such cases is chosen so that the material thickenings are hindered from slipping out of the slits. In such embodiments of the arrangement the retaining means 64 or control means 66 are provided with slits and are thus adapted to the package band described above. - In certain applications of the invention the
discharge base 60, as mentioned already, is designed with, or as a, conveyor belt against which rests thefirst wall 11a of the package band. The conveyor belt then completes and/or substitutes the transportingarrangement - The foregoing detailed description made reference only to a limited number of embodiments of the invention, but it will be obvious to those versed in the art that the invention encompasses a great number of embodiments within the framework of the following claims.
